Product Description:

The RKL4806 cable is manufactured by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. This flexible assembly carries motor power and auxiliary control signals between Indramat drives and servomotors, allowing coordinated motion in gantries, pick-and-place modules, and other automated axes where the connection must follow continuous movement. Its construction is tailored for dynamic routing inside energy chains and maintains electrical integrity during millions of operating cycles within industrial automation cells.

The cable is designed to withstand up to 5,000,000 flexing cycles, supporting high-duty gantry and robot operations. When installed in continuously moving tracks, the minimum dynamic bend radius is 7.5 × D, while static routing requires a minimum bend radius of 5 × D. These limits protect the conductor geometry and shielding from deformation. An outer diameter of 10.0 mm keeps the bundle compact for narrow energy-chain compartments, and the PUR jacket resists abrasion, oils, and coolants encountered on factory floors. Orange sheathing in accordance with RAL 2003 provides quick visual identification, and the cable is suitable for drag-chain use.

Four 0.75 mm² power conductors carry phase current, while two shielded 0.5 mm² control conductors transfer brake or sensor signals with low noise pickup. The insulation system withstands a continuous core temperature of 80 °C, enabling operation close to servo housings and inside sealed enclosures. The power and control conductors use separate voltage classes to maintain signal isolation. The power cores are rated for 300/500 V, whereas the control conductors are rated for 300/300 V. Tinned copper grounding conductors and an overall braided shield help maintain stable voltage delivery and electromagnetic compatibility throughout the cable’s service life. The separated conductor groups also reduce interference between motor power and low-level brake or sensor signals during continuous movement.
